That's where a mirror comes in.  I have a similar situation for myself -- I
hack on my (frequently disconnected) laptop, and then push changes out to
the mirror on my website for the archives that are likely to be of interest
to anyone else.

Your developers could do a similar thing -- have their own private archive
on their laptops, mirror it to (say) your company webserver (or intranet, or
whatever) and then everyone else can register those mirrors and work from
those.

There appears to be a missing command there -- between those two tla
commands there should be a 'cd merge-temp'.  As per the 'get' docs, that
final argument specifies a directory to put the checked-out tree into.

The set of changes between the current working copy and the specified
revision (hello-world--mainline--0.1--patch-<last>) is calculated, and then
applied to the current tree.  You should then review the applied changes,
fix any conflicts, and then commit those changes to your tree, thus
completing the merge.

Caveat: Don't do a merge into a tree with uncommitted changes.  It can be
done, but it's a bit messy.

Largely irrelevant.  Nothing is changed in the mainline by your merge.

candice just got stuff from mainline in the previous commands.  If she wants
to merge again, she re-runs the exact same command, and tla is clever enough
to work out what to merge and what not to re-merge.

The alternate action, where mainline wants candice's changes, is a
star-merge again -- this time, we get hello-world--mainline--0.1 and then
tla star-merge address@hidden/hello-world--candice--0.1.

Feel free to fix up any typos you find.  It doesn't look like they're
mandating registration for edits yet.
